Today, Apple is unleashing Mac OS X 10.5 Leopard onto the world. It's already available to people in Australia and New Zealand (you liking it, Kaiwai?), and Europe and the US will follow later today. There's an article on what's new for Ruby developers, while others want to figure out what Leopard means to the 'enterprise' (I love those silly business terms). Update by AS: My copy of Leopard was slated for a 10AM delivery, but didn't arrive. I called FedEx and a CSR told me that an internal memo was just released; Apple has apparently waved the shipping deadline for all packages today and requested delivery be rescheduled at the end of the business day. Update 2 by AS: Ok, we've received our copy. How about you other US'ers?
